NAME

soldout_renderers, lus_attr_escape, lus_body_escape — various markdown to HTML renderers for soldout

SYNOPSIS

#include <renderers.h>

void
lus_attr_escape(struct buf *ob, const char *str, size_t len);

void
lus_body_escape(struct buf *ob, const char *str, size_t len);

extern const struct mkd_renderer mkd_html;
extern const struct mkd_renderer mkd_xhtml;
extern const struct mkd_renderer discount_html;
extern const struct mkd_renderer discount_xhtml;
extern const struct mkd_renderer nat_html;
extern const struct mkd_renderer nat_xhtml;

DESCRIPTION

The lus_attr_escape() and lus_body_escape() functions escape all problematic characters in (X)HTML: ‘<’, ‘>’, ‘&’, ‘"’; and ‘<’, ‘>’, ‘&’ respectively. They accept a string str of the length len and output into ob buffer.

All provided renderers come with two flavors, _html producing HTML code (self-closing tags are rendered like this: <hr>), and _xhtml producing XHTML code (self-closing tags like <hr />).

mkd_html and mkd_xhtml implement standard markdown to (X)HTML translation without any extension.

discount_html and discount_xhtml implement on top of the standard markdown some of the extensions found in Discount and PHP-Markdown-like tables. Here is a list of all extensions included in these renderers:

• image size specification, by appending "=(width)x(height)" to the link
• pseudo-protocols in links:
  • abbr:description for <abbr title="description">...</abbr>
  • class:name for <span class="name">...</span>
  • id:name for <span id="name">...</span>
  • raw:text for verbatim unprocessed text inclusion
• class blocks: blockquotes beginning with %class% will be rendered as a div of the given class(es)

nat_html and nat_xhtml implement on top of Discount extensions and Natasha's own extensions. Here is a list of these extensions:

• id attribute for headers, using the syntax id#Header text
• class attribute for paragraphs, by putting class name(s) between parenthesis at the very beginning of the paragraph
• <ins> and <del> spans, using respectively ++ and -- as delimiters (with emphasis-like restrictions, i.e. an opening delimiter cannot be followed by a whitespace, and a closing delimiter cannot be preceded by a whitespace)
• plain <span> without attribute, using emphasis-like delimiter |

RETURN VALUES

The lus_attr_escape() and lus_body_escape() functions do not return a value.
